This product measures 1-1/2" in diameter, and 3/8" in thickness and features a 1.065" hole going through the thickness of the magnet. It is made of a grade N45 neodymium, iron, and boron magnetic alloy blend. This magnetic blend is patent licensed and made under the ISO 9001 quality control systems. They are plated in a nickel-copper-nickel triple layer coating for a shiny corrosion resistant finish. Neodymium ring magnets are perfect for use as magnetic fasteners around the home and for use in commercial applications.

Please note that all neodymium rare earth magnets are fragile and require caution when installing to prevent shattering the magnet due to their brittle nature, and when handling to avoid injury due to pinching

  • Good big one.

    Great magnet. Pretty strong to where it will fly out towards other magnets, but the shape, size and (limited) heft give it a good hold in your hands. Also, this magnet did not have the smooth chrome-like nickel finish but instead a more matte-silver finish with machine lines on the OD, but I find that super cool
